AUTOMATIC FEEDER FOR PRINTING AND OTHER PRESSES. v

SPECIFICATION forming part of Letters Patent No. 246,473, dated August30,.1881.

Application filed November 13, 1860. (ModeL) Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a new andvaluable Improvement in Automatic Feeders for Printingand other Presses;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 is a perspective view of the device. Fig. 2 is detail showingthe griper. Figs. 3 and 4 show different positions of the holder.

Fig. 5 is a detail showing the toothed roller and stop. Figs. 6 and 7are details showing thetappets on the main shaft. Fig. 8 is an end view,showing the connection of the rock-shaft with operating mechanism.

Thisinvention relates to the feed for presses and its object is torender such feed automatic.

It consists in the construction hereinafter specified in the claims.

In the annexed drawings, A is a platform for receiving the pile ofsheets to be fed forward to the machine. This platform extends over theedge of a table, A as clearly shown in Fig; 8, though the platform andtable may be constructed as one. At its rear end, a, is located a post,13, to which is pivoted a griper, 0, whose hooked end 0 is held downupon the sheets by a spring, b. Upon the other side of said post B, byan arm, 61, is hinged a holder, D, whose forward end is composed ofbranches 6 g, the former and top one extending beyond and up from thelower one, the two forming a slot, h.

To one side of platform A is hung, upon shaft F, a bracket, E, whichextends across said platform, and has at its ends forks,between which isjournaled a roller, Gr, said roller being to the same side of post B asforked holder D, and on a line with hooked end 0 of griper 0, both beinga littlein front of the line of post B.

Fastened to shaft Fis an arm,H,from whose end a a chain, I, extends upover roller K upon bracket E, down to and around roller G. This rolleror wheel Gr has its periphery made of blunt teeth, and is turned in thedirection of the arrow by the chain I and returned by a spring. To therear end of this rollerK is socured an arm, D,the front end of which isheld in a guide-loop, d, at the end of bracket E. The extremepointofthis arm D, takingagainst the post B and acting as astop,keeps theroller G from going too far. Shaft F is hung in bearings ff, and gearsby a bevel-wheel with another upon shaft L, turningin hearingsp p.

Behind post B, and to the side upon which is griper U, is a bracket, M,havingarms m 122,

between which is pivoted a frame, N, whose rod R is connected by a wire,8, to griper C. To the rear of the frame N, upon the shaft L, is locateda cam, t, adapted to strike said frame N at the proper time.

To the same side of sh aftL as bracket M, but to the other side of postB and holder D, is located another bracket, M, carrying frame X, whichlatter engages pins z 2 on arm at of holder 1). On shaft L, back of thisframe, are secured two sleeves, \V and X, the former having therule-jointed tappet w and rigid cam-tappet W, and the latter the rigidcam-tappet m, the camtappets projecting in opposite direct-ions.

Attached to shaft L is the arm S, through which said shaft has a rockingmotion.

To the front end of platform A is inclined a frame bearing in front thefeed -shaft V, having feed-rollers. In front of this shaft is locatedthe feeding device usually in use in these machines. A pile of sheets isplaced upon platform A, with the feed-rollers of shaft V upon theirfront ends, and the hooked end 00f griper (1, arm D, and wheel G upontheir rear ends.

Power is communicated to rock-shaft L through arm S, turning said shafttoward the platform A. This causes sh aft 1' to also turn toward theplatform, pushing arm H downward, drawing on chain I, and causing wheelG to turn as indicated by the arrow. As the griper 0 holds the otherside of the sheets fast, this rotary action of the wheel G causes itsteeth to buckle up theleaves, especially the uppermost one, against theresistance of the griper. The holder D being very light, this bucklingraises it, and the top sheet drops into the slot h. At this point thetappet W, striking the frame X, causes the latter to turn on its pivotsand, through the forward pin 2, thrust the hold er forward, so that theupper sheet is held well in the slot h, whereby the holder operates as alifter at the proper time. As shaft L returns tappetVVis lifted fromframeX; but thejoin ted tappet w, coming up, locks the frame forward,until the tappet t, operating on frame N, shall have withdrawn thegriper from the top sheet, when the feed-rollers on shaft V catch it,hearing it 011'. At this moment both tappets t and 'w are drawn fromtheir respective frames,

and the spring I) returns the griper and the tappet w by hearing on itsheel the frame X and holder D. While this is proceeding,wheel G willcease to revolve, the chain I running out, and further strain on saidchain causes bracket E to rise and lift wheel G from off of the pile ofsheets, when all will fall except the one held in holder 1). As shaft Lturns so as to return the griper and holder for the next sheet thebracket and its attachments are also returned.
